L20 Structure of Major Brain Areas, Basic Sensory and Motor Pathways

Frage 1 von 14

1

Choose the correct statements about the external anatomy of the brain.

Wähle eine oder mehr der folgenden:

  • The central sulcus sits between the frontal and parietal lobes.

  • The parieto-occipital sulcus is anterior to the central sulcus.

  • The lateral sulcus is superior to the transverse fissure.

  • The pre-central gyrus and the post-central gyrus sit on the parietal and frontal lobes respectively.

Erklärung

Frage 2 von 14

1

Choose the incorrect statement about the function of the brain's lobes.

Wähle eine der folgenden:

  • The parietal lobe is primarily concerned with sensory information.

  • The occipital lobe is primarily concerned with vision.

  • The temporal lobe is associated with memory and hearing.

  • The frontal lobe is primarily concerned with motor information.

Erklärung

The is split into two regions, the .
The motor cortex is split into two regions: the cortex which sits on the gyrus, and the cortex, the anterior region of the motor cortex which . Together they control somatic efferent signals.
The pre-frontal cortex is involved in . to it can result in a change of personality, and of it can be altered by alcohol. It is abnormalities in this area which can cause personality altering mental illnesses such as .

Frage 7 von 14

1

The cerebral cortex (white matter) is superficial to grey matter of the brain.

Wähle eins der folgenden:

  • WAHR
  • FALSCH

Erklärung

Frage 8 von 14

1

Choose the correct statements about the internal anatomy of the brain.

Wähle eine oder mehr der folgenden:

  • Deep collections of cell bodies (grey matter) are called deep nuclei.

  • The 3 types of white matter are differentiated by orientation.

  • The commissural tracts join the cerebral hemispheres. E.g. The corpus callosum

  • The corticospinal tract is an association tract.

  • Projection tracts are communication pathways between regions of the same side of a cerebral hemisphere e.g. pre-motor and motor cortex pathway

Erklärung

Frage 9 von 14

1

The primary motor cortex sits on the pre-central gyrus, and it's neurons have no specific organisation.

Wähle eins der folgenden:

  • WAHR
  • FALSCH

Erklärung

Frage 10 von 14

1

Which statement about the corticospinal tract is false?

Wähle eine der folgenden:

  • It is a projection tract

  • It contains efferent neuron cell bodies

  • Most of its fibres cross over to the opposite side of the body in the medulla oblongata

  • Axons synapse in the dorsal horn of the spinal cord

Erklärung

Frage 11 von 14

1

Choose the incorrect statement about the somatosensory pathway

Wähle eine der folgenden:

  • The 'relay' neuron between the spinal cord and the thalamus resides in the medulla oblongata

  • The flow of information crosses over to the opposite side when passing through the relay neuron, before ascending to the thalamus

  • There is another synapse between the neuron from the thalamus and somatosensory cortex (in the parietal lobe)

  • The mapping of the somatosensory cortex is the opposite to that of the motor cortex.

Erklärung

Frage 12 von 14

1

The neurons in the somatosensory cortex have very short, or no axons, while the neurons in the motor cortex have relatively longer axons.

Wähle eins der folgenden:

  • WAHR
  • FALSCH

Erklärung

Frage 13 von 14

1

The cerebellum motor and sensory systems, movement guided by sensory feedback.
Firstly, the cortex initiates an AP for movement. This is copied/relayed to the . Next, information about the movement goes to the cerebellum. The cerebellum these sets of information, and the motor output (coordination).

1

Choose the incorrect statement about the basal ganglia

Wähle eine der folgenden:

  • There are 5 types of basal ganglia (groups of cell bodies in the brain)

  • The substantia nigra are the basal ganglia which cause Parkinson's disease when they fail to function

  • The basal ganglia are part of a circuit in a brain and their role is to select an appropriate movement

  • The basal ganglia are not involved in initiation or termination of movement
